The invention relates to the technical field of elevators, in particular to a forced driving host for an elevator. The forced driving host comprises a motor, a speed reducer, winding drums and steel wire ropes; the speed reducer is connected with an output shaft of the motor; the winding drums are located on the two sides of the speed reducer, the output part of the speed reducer is connected withthe winding drums to drive the winding drums to actively rotate; and one end of each steel wire rope is fixed on the winding drums, the other end of each steel wire rope is connected with a lift car,and the steel wire ropes are wound on the winding drums. In the forced driving host for an elevator, the two winding drums are arranged and located on the two sides of the speed reducer, so that twosets of steel wire ropes can be arranged, the operation is more stable while the load capacity is improved; and a wire jumping prevention mechanism is arranged, so that the steel wire ropes are prevented from making contact wit
